Battery-Powered Grass Trimmers

These trimmers are powered by rechargeable batteries and are cordless, making them more convenient to use than corded trimmers. They are ideal for small to medium-sized lawns and are quieter than gas-powered trimmers. However, their batteries can run out quickly, so they may not be suitable for larger yards.

Gas-Powered Grass Trimmers

These trimmers are powered by gasoline and are ideal for large lawns or areas with heavy weeds and overgrowth. They are more powerful than electric or battery-powered trimmers, making them suitable for tougher jobs.

How to use a Grass Trimmer

Using a grass trimmer, also known as a strimmer or weed whacker, is a great way to maintain a neat and tidy lawn and these are some steps you can follow when using a grass trimmer to maximise your potential results

1, Prepare the trimmer: Before using the trimmer, ensure that the line is properly loaded and that all safety features are working correctly. Wear appropriate clothing, including long pants, closed-toe shoes, and eye and ear protection.

2, Adjust the height: Adjust the height of the trimmer so that the line is just above the ground. This will prevent the line from wearing out too quickly and ensure that the trimmer is cutting effectively.

3, Start the trimmer: If using an electric trimmer, plug it into an electrical outlet. If using a gas-powered trimmer, prime the engine and pull the starter cord to start the engine. Let the trimmer warm up for a few minutes before using it.

4, Begin trimming: Hold the trimmer at a slight angle and start trimming around the edges of the lawn. Work in a clockwise or counter clockwise direction, depending on your preference. Move the trimmer slowly and steadily to avoid damaging plants or trees.

5, Trim around obstacles: When trimming around trees, plants, or other obstacles, hold the trimmer at an angle and move slowly. Take care not to hit any obstacles with the line as this can cause damage to the trimmer and the object.

6, Finish trimming: Once you have completed trimming the edges of the lawn, move to the centre and work your way outwards. Take care not to step on any cut grass or debris as this can damage the lawn.

7, Clean up: Once you have finished trimming, turn off the trimmer and clean up any debris or cut grass from the lawn. Using a grass trimmer is relatively easy and straightforward. By following these simple steps, you can keep your lawn looking neat and tidy all year round. Remember to always wear appropriate safety gear and take care when using the trimmer around obstacles or delicate plants.

Main Components of Grass Trimmers

Although quite basic, these are the main components that make up a grass trimmer for your lawn so that you can be familiar with all the different parts involved

Motor or Engine

The motor or engine is the power source for the trimmer. Electric trimmers have an electric motor, while gas-powered trimmers have a combustion engine. The motor or engine powers the cutting head, which cuts through grass and weeds.

Cutting Head

The cutting head is the part of the trimmer that cuts through grass and weeds. It contains a spinning spool that holds a length of cutting line, which is fed out as needed. Some trimmers also have metal blades that can be attached to the cutting head for tougher cutting jobs.


The shaft connects the motor or engine to the cutting head. It is usually made of metal or plastic and can be adjustable in length to accommodate different users or cutting angles.


The handle is where the user grips the trimmer to control its movements. It can be a looped handle, which allows for better manoeuvrability, or a straight handle, which provides more stability.

Trigger or Throttle

The trigger or throttle is located on the handle and controls the speed of the motor or engine. Squeezing the trigger or throttle will increase the speed of the cutting head, while releasing it will slow it down or stop it altogether.


The guard is a safety feature that is designed to protect the user from flying debris, such as rocks or sticks, that may be kicked up by the cutting head. It can be a plastic shield that surrounds the cutting head or a metal plate that covers the bottom of the cutting head.

How to Maintain a Grass Trimmer

Maintaining your grass trimmer is essential to keep it running smoothly and effectively and these are some tips on how to maintain a grass trimmer for the long term future

1, Clean the trimmer - After each use, clean the trimmer to remove any grass or debris that has accumulated on the cutting head, shaft, and guard. Use a brush or rag to wipe away any debris, and avoid using water or other liquids, as this can damage the motor or engine.

2, Check the cutting line - Check the cutting line regularly to make sure that it is at the proper length and is not worn or damaged. Replace the line as needed, and ensure that it is loaded properly onto the cutting head.

3, Check the air filter - If you have a gas-powered trimmer, check the air filter regularly and clean or replace it as needed. A dirty or clogged air filter can cause the engine to run poorly or not at all.

4, Check the spark plug - For gas-powered trimmers, check the spark plug regularly and replace it if it is dirty or worn. A clean spark plug will help the engine start more easily and run smoothly.

5, Check the fuel filter - If you have a gas-powered trimmer, check the fuel filter and replace it if it is dirty or clogged. A clogged fuel filter can cause the engine to run poorly or not at all.

6, Store the trimmer properly - When not in use, store the trimmer in a dry, cool place. Remove the cutting line from the cutting head, and cover the trimmer with a protective cover or tarp to keep it clean and free from dust or debris and all of these tips can ensure that your trimmer is always ready for use when you need it, and that it will last for many years to come.
